Solver Foundation is a pure, managed code runtime for mathematical programming, modeling, and optimization. This .NET/CLR based framework provides a rich set of tools, services, and engines to aid companies in their continuous quest for operational efficiency, profit maximization, and risk management. Solver Foundation is designed to help businesses make strategic decisions. It affords its users the advantage of easy to use tools, numerically stable solver technologies and deep integration with ubiquitous information worker systems like Microsoft Office.Solver Foundation uses a declarative programming model, consisting of simple compatible elements that are solved by application of solvers, meta-heuristics, search techniques, and combinatorial optimization mechanisms to accelerate the solution finding process. Building a model in Solver Foundation is as simple as specifying the decisions to be made, constraints to be respected, the goals to be used to evaluate candidate proposals (solutions) and the data to be processed by the model (historical or projected parameters). This can be done from any CLS-compatible language and the modeler does not need to understand anything about the details of solver technologies or search strategies. The separation of concerns is total, providing a high degree of modularity.
